ANSWER- Innervated by median nerve for 1st 2 fingers and ulnar nerve for ring and little finger Flexes DIP, PIP & MCP joints Flexor Pollicis Longus - ANSWER- Innervated by the median nerve Flexes IP and MP joints of the thumb Pronator Quadratus - ANSWER- Innervation: Median nerve Pronation of the forearm Carpal Tunnel - ANSWER- All flexor tendons and the median nerve enter the carpal tunnel beneath the flexor retinaculum In the canal the common profundus tendon to long, ring and little fingers divides into individual tendons Extensor Carpi Ulnaris - ANSWER- Innervated by the radial nerve Extension of the wrist Ulnar deviation of the hand Extensor Digitorum Communis - ANSWER- Innervated by the radial nerve Extends fingers Extensor digiti quinti proprius - ANSWER- Innervated by the radial nerve Extends the little finger Brachioradialis - ANSWER- Innervated by the radial nerve Pronation and Supination depending on position of the forearm Extensor Carpi Radialis Longus and Brevis - ANSWER- Innervated by the radial nerve Extension of the wrist Radial deviation of the hand Extensor Pollicis Longus - ANSWER- Innervated by the radial nerve Extension of the thumb IP joint Extension and Abduction of the thumb MP and CMC joint Supination of thumb MP joint Extensor Indicis Proprius - ANSWER- Innervated by the radial nerve Extension of the index finger Muscles of the Thenar Eminence - ANSWER- Abductor Pollicis Brevis Flexor Pollicis Brevis Opponens Pollicis Adductor Pollicis Muscles of the Hypothenar Eminence - ANSWER- Abductor Digiti Quinti Flexor Digiti Quinti Opponens Digiti Quinti Palmaris Brevis Abductor Pollicis Brevis - ANSWER- Innervated by the median nerve Abduction of the thumb Flexion of thumb and MP and CMC Flexor Pollicis Brevis - ANSWER- Superficially innervated by median nerve Deep innervated by ulnar nerve Flexes and Rotates thumb Opponens Pollicis - ANSWER- Innervated by the median nerve Allows opposition to fingers Adductor Pollicis - ANSWER- Innervated by ulnar nerve Adducts thumb to palm to give power to grasp Abductor Digiti Quinti - ANSWER- Innervated by ulnar nerve Abduction of little finger Flexion of proximal phalanx Extension of PIP and DIP Flexor Digiti Quinti - ANSWER- Innervated by the ulnar nerve Flexion of proximal phalanx Rotation of 5th MC Opponens Digiti Quinti - ANSWER- Innervated by ulnar nerve Draws 5th MC anteriorly and rotates laterally for opposition with thumb Palmaris Brevis - ANSWER- Innervated by ulnar nerve Wrinkles skin of the ulnar side of the palm, deepens hollow of palm aiding grip Covers and protects ulnar nerve and artery Interosseus Muscles - ANSWER- Seven 4 Dorsal 3 Palmar Important for movements needed to write, type and play piano Dorsal Interossei - ANSWER- - Innervated by ulnar nerve - spread to index and ring finger Palmar Interossei - ANSWER- Innervated by ulnar nerve Adduct index, ring and little finger The Lumbricals - ANSWER- Innervated by median nerve from index to 1st finger Innervated by ulnar nerve for ring and little finger Supplement MCP flexion and Extension of PIP and DIP Median Nerve Supplies... - ANSWER- - Pronator Teres - Palmaris Brevis - Flexor Digitorum Profundus (2nd and 3rd fingers) - Flexor Pollicis Longus - Palmar Cutaneous Brach - Superficial branch to Flexor Pollicis Brevis - Opponens Pollicis - 1st and 2nd Lumbrical - Palmaris Longus - Flexor Digitorum Superficialis - Prontator Quadratus - Abductor Pollicis Brevis - Digital Sensory Nerve Ulnar Nerve Supplies... - ANSWER- - Flexor Carpi Ulnaris - Flexor Digitorum Profundus (4th and 5th Digit) - Abductor Digiti Quinti - 3rd and 4th Lumbrical - Palmar Interosseous - Flexor Pollicis Brevis - Adductor Pollicis Radial Nerve Supplies... - ANSWER- - Extensor Carpi Ulnaris - Extensor Digiti Quinti Proprius - Extensor Pollicis Longus - Extensor Carpi Radialis Brevis - Extensor Digitorum Communis - Brachioradialis - Extensor Carpi Radialis Longus - Extensor Indicis Pollicis When median nerve is severed at the elbow... - ANSWER- - Flexion of PIP joint of thumb, index and middle finger is lost and weakened in ring and little finger - Flexion of DIP joint of index and middle finger is also lost - Ability to flex MCP joint of index finger is affected - Thenar muscles are lost as in CTS - When making a fist index and middle fingers will stay partially extended Injury to ulnar nerve at distal art of forearm - ANSWER- Denervated most intrinsic muscles of the hand, power of adduction is impaired which can lead to a claw hand appearance as the interosseous muscles atrophy Radial nerve injury when humerus is fractured - ANSWER- This injury is proximal to the branches of the extension of the wrist and so wrist drop is the first clinical sign of an injury at this level Radial nerve injury at a deep branch - ANSWER- Results in an inability to extend the thumb and MCP of other fingers How to test if a deep branch of the radial nerve is injured - ANSWER- Ask the patient to extend MCPs against resistance
